What moves the number
Summer demand spikes both prices and wait times — a July capacitor job can hit the top of the range while the same fix in February is cheaper and faster. Older R-22 systems cost more to recharge. Two-story homes and attic units (common in SA) add labor time. Efficiency upgrades (SEER2 ratings) push replacement cost up but cut CPS Energy bills meaningfully in summer.
How to get an honest quote
Get the repair-vs-replace math in writing: if the fix exceeds ~30% of a new system's cost on a 10+ year unit, replacement usually wins. Ask whether the capacitor was OEM-rated — cheap caps fail again within a season. Check CPS Energy for current AC rebate programs before replacing.
